Based in California, OakTree Aviation Services delivers personalized aircraft appraisals to both individual and institutional clients. Our comprehensive approach involves inspecting aircraft on-site, scrutinizing maintenance logs and records, and conducting market-driven analysis to produce credible, defensible reports.
With expertise spanning three decades, we efficiently serve a broad range of locations across the Inland Empire, Orange County, Los Angeles, and San Diego, and accommodate inspections at both public and private airports. When you contact us, you'll be connected with a small, dedicated team, not a generic call center. We take the time to understand your unique needs and circumstances.
From financing and estate planning to legal matters and tax reporting, our team of experienced professionals provides high-quality appraisals for a variety of purposes, adhering to established industry standards and ensuring clear documentation to support confident decision-making.

Our appraisal practice includes valuing fixed‑wing and rotor‑wing aircraft in the general aviation and business aviation markets.
Depending on the assignment’s requirements, we provide USPAP‑compliant aircraft appraisals as well as certified non‑USPAP reports. In all cases, our work is supported by PAAO analytical methodology, with clear identification of intended use, intended users, scope of work, and effective date.

OakTree Aviation Services maintains deep operational roots in California and routinely performs on‑site aircraft inspections throughout Central and Southern California, supporting appraisal assignments across the state.
Our appraisal practice also includes aircraft located throughout the Western United States, including Oregon, Washington, Idaho, Nevada, and Arizona. Assignments are structured to accommodate inspection logistics, regional market conditions, and the specific requirements of the intended use.
Whether an aircraft is located within California or elsewhere in the United States, appraisal assignments are handled with a consistent, methodical approach grounded in market evidence, professional judgment, and defensible analysis.

We provide aircraft appraisal services with local inspection capability and nationwide coverage, supporting assignments where the aircraft, lender, attorney, fiduciary, or owner may be in different regions.
Depending on the assignment’s requirements, we prepare USPAP‑compliant aircraft appraisals as well as certified non‑USPAP reports. In all cases, reports are structured for professional reliance, with clearly defined intended use, intended users, scope of work, and effective date.
